Choi misses out on title - and big pay day

Choi Hye-jin has a win on the Korean LPGA Tour and a top-10 finish on the LPGA Tour

Amateur Choi, 17, went into the final day a shot adrift of Feng and was in contention for the title until she stepped onto the tee at the par-three 16th.

Her tee shot at the 140-yard hole disappeared into the water as she went at the pin tucked tight to the right side - and with it went her hopes of the win as she recorded a double-bogey five.

Choi recovered her composure to birdie 18 to finish two clear of world number one Ryu So-yeon and another South Korean, Hur Mi-jung, but two behind Park.

She had been attempting to become only the second amateur to win the US Women's Open in its 72-year history, after Catherine Lacoste of France in 1967.

As an amateur, Choi also missed out on the runners-up prize of $540,000 (£412,700) - but said the experience was worth far more.

"It will be nice if I could get the money but I think my primary goal was to come here and compete so, to me, getting this second place as runner-up actually means more to me and it's a greater honour," she said.

"Even if I could just come and play, that alone would be an honour, but I get the runner-up and it is unbelievably joyous thing for me."

Choi was also the low amateur in 2016, finishing 38th at CordeValle in California.
